IMPRVEMENT IN SELF-ACTING- MULE FOR SPINNING.' l

The Schedule referred to'in these Letters Patent andrmakng of the same.

To all lwhom it may concern Be it known that I, WILLIAM HA CKLEY, of Moosnp,

in the town of Plainfield, county ofWindham, and State' of Connecticut, have inveiited certain new and useful Improvements in the Mason Self-actin g Spinnin g-Mnle, so-called; and I do hereby declare the following to be Y a full, clear, and exact description of the saine, reference being had to the accompanying drawings making a p'art thereof, in whieh-J Figure I represents a vertical, and

Figure 1I, a side view of the improvements, with so much-of the mule and its arrangements as are nece-ssary to showsaid improvements.v ,I

Figure III represents the shaft Xwit,h the clutchgear FFE, the bentbar E5, the ratchet E, the pawl El, the loose gear E", and the spring E.

Figure 1V shows the fast rim-pulley G1, containing the ratchet G, and the pawls G3.

Figure V, the openings on the disk of the clutch E.

Figure VI, the catch-gear Fl F, the finger F4, the end of' the lever J, and the friction-clutch F5 C2 on the shaft F2.

The same parts in thedifierent figures are indicated by the sameletters.

The invention relates to the backing-off and winding-on motions of' the mule, and which are in opera,- tion from the'time the`driving-belt is transferred to the second driving-pulley A until it is carried back to the first, and includes, also, modes of regl'llatingA the starting ot' the mule-carriage in ruiming in. orout.

It consists in improving and simplifying the apparatus now employed, in part,by substituting new de vices and, in part, byv dispensing with the regulator and other arrangements heretofore considered essen- `tial in running said mule.

By dispensing with the machinery hereinafter men tioned, -the amount of power required torun thenule, its liability to derangement and breaking down, and the expense of repairs as well as the loss in time and production, 'are lessened.

By vmy alterations the mule is improved in these respects, vizz that :while in the present Masonfmule.

the mot-ions above mentioned are'not always certain, and the apparatus sometimes gets out of order and breaks, under the plan hereinafter described the first vare made exact and positive, andthe machinery selfrom that point, to continue and finsh'the operation without breaking the yarn-or dera-ngin g the machinery.

The backing off and winding on can, besides, be

effected more rapidly, thereby enabling themule to produce more yarn.

The improvements do not affect nor alter the appae ratus'or gearing connected with the movement 'of the carriage, except to bring the running-in mot-ions into gear promptly, and to modify and graduate the.motion. I

of the carriage so as to prevent a violent and abrupt starting when commencing to run in or ont; or, the apparatus now used to regulate the speed of they spindie to the size of the' cop rin windingon, or the positionof the cop-rail for the same purpose, butare eenfined to the inode of operating thefriction-band pulley E, its shaft and connections, with the usualnpper rack D, the cop-rail shaftN, the shaft F2, usually known as the scroll-clutch shaft, and a friction-gear, S', on the shaft'S.

In ygeneral terms these may bc enumerated as foilows, viz:

Theband-pnlley E and the band are stopped and the reverse motion effected by friction alone. When the frictionis removed thepulley is simultaneously connected with the rack D2 so that they are operated alike by the same power and run in correspondencel while the yarn is winding on,

. As an exact and positive action is thus produced, and the backing of' no longer obliges the friction-band pulley tomove the rack DJl when'its motion is reversed',

as in the.M`ason mule, the apparatus on the rock or clutch and clntehfgear' are for the same reason dispensed with.

l In order to make the connection more exact andcertain between the gear F during the running-in motion, and the second:'drivingfpulley A`, instead of' the scroll-clutch gear, catch-gear-"Fl F is used, and' a different mode is employed to'keep these from coming into Contact, and to regulate them after" the belt has been thrown onto the pulley A, and while the backing-off is takingplace.

'lo produce a steady starting motion when the carriage is about ruiming in or out, instead of making gear.C.2fast'to the'sliaftFz, or the gear R to the shaft S, cach is allowed to run loose on its s haft, and the connection of the gear C'3 to `the running-in gear,and

that of gearlt to the runnii-ig-out gear, is produced by'A bringing the faee'or disk of a friction-pulley, adjustedl and made fast on the shaft, intocontact with the face drawings making part of this specification.

On the main 'shaft A2 is added'a gear, B, running loos'ely on the shaft with and attached to the second driving-pulley A.

Gear B1, on shaft B, meshes with B, and on the other end of this shaft is gear B2, which plays into nnd'operates gear B3, attached to the friction-pulley N, both running loosely on. shaft X. The shaft X also carries a band-pulley, E, and the ratchet-gear E6, both secured upon it, and a vloose gear, E, which, through a, "rain of wheels, connects with the upper rack D4; also a pair of clutch-boxes, Ez and E, and a bent bar, E, around the collar of the clutch E?, (one end of which har is secured by a pin to the -pawl E2) all likewise loose. The shaft slides endwise in its bearings.-

On the other end of the shaft is applied the end of a spring, E9, secured to the muleframe,`and of sufficient strength to press the band-pulley away from the frietion-pulley anddestroy the friction caused by its contact with the friction-pulley when no counter-force is in action.

The paw] ET is pivoted to a pin on the side of the loose gear E, and is arranged to hang over theratchetgear E, and to turn on its bearing. The rear end of the pawl has a lip which by the pin is connected with the bent bar E5.

The clutches E2 and "a are' confined within certain limits, viz: E2 by a pin, K2, let down from the shipper K, and by the arm E4.

E is attached through a rod, J', to the arm of the lever J'.

Clutch Ez has two projections, and El has corresponding openings `of' the shape and size to vreceive them.

The band-pulley G, instead of revolving on a stud, is set fast upon a revolving shaft, Y, upon which a fast pulley, G1, is also set, having a hollow rim.

To 4the'unde'r surface of this rim Aare secured several pawls Grs G playing' loosely, so that when the shaft and vn'm-pulleyturn in one direction these pawls pass over the teeth of a ratchet-gear, G, (which is placed loosely on the shaft and within the 1'im,) with; out catching them, but when turned in the other direction they enter and carry the ratchet and the pulley G, to which it is attached, with the chains Gr5 and G, fastened at one end tothe periphery of the pulley G4, in the same direction.

One of lthese chains G5 acts simply to keep the other chain GG taut, and for this purpose is carried over a loose pulley, and has a weight, G7, suspended from it.v The other, G, passes down over the periphcry of a half-heart cam, H, and is fastened to it where the radins is diminished.

Y The cam His set on the cop-rail or rock-shaft N, which is turned in its bearings by the chain G in one, and by the weight of the cop-rail in the other direction.

This shaft has, besides the arm connecting it wit-l1 the cop-rail, the pulley L, (made without the pins or spurs,) around which the chain L1, connecting the rack D* and the weight L?, passes, and also an arm to which the rod Z, connecting the curved arm Z and the rod or bar U, are attached.

The other apparatusv now used Yto regulate and operate therack l)4 on this-shaft, and connected with it, is removed `as useless, and leather or other straps of riinger F4 from the shifting apparatus.

sufhcient strength may be substituted fortlie chains L1, Gand G5. l i

On the shaft F2, catch-gear F Fare substituted for the scroll-elut-ch, so called.

FiI is attached to the gear F.

F1 slides endwise on the shaft, and is operated by It is made with projecting shoulders or collars, which, when the end of the lever J 'is in contact with the gear, prevent the two from closing. i

The shaft also carries the loose gear G2, which is connected byV intermediate gear with the pulley A,

and a friction pulley, F5, made fast onthe shaft, tting into the face or disk of C2, and which is pressed against it by a suitable spring fixed on the frame, and acting on the end of the shaft which, for the purpose slides, endwise.

On the shaft S` carrying the gear T, which through intermediate gear operates to run the carriage out, instead of a fast gear, I introduce a loose-gear, R, and a fast friction-pulley, S", arranged to run face 'to face, and adjust-able so that, while the ordinary power is operating, the contact will produce the friction to drive the shaft S as efectually as` if the gear R was fast upon the shaft; but, should any derangement of machinery produce an unusual strain, lthe friction will yield to the excess of power and preserve thermachiue'ry from breaking. v v v The lever J, one end of whichv is connected by the rod or bolt J l to the arm l* of the clutch E, has its fulcrum on the stud J2, and is carried beneath the gearing and driving-pulleys, and, at the other end, is terminated by a. broad face, attened to be pressed against the recess formed by the shoulders of catchgear F1. v v

'lo this last arm of the lever J Vis connected, by a slotted rod confining a bolt secured to it, the arm J 3 set upon shaft YV.

Thisshaft rotates on bearings secured to the flame M, and carries also the arm V. On the end of the arm V is a pin, t". v 4

The rod U, above 1nentioned,is extended beyond the arm Q. Near its extremity a short adjustable bar, U', is set, and secured by a set-screw upon it. The arm Qr piece connecting the two forms a right-angle with the lower bar, and answers as a hook to hold the pin c', and may be rounded off at the corner of the upper bar. p.

The ends of the two bars pass through and slide in holes in a stand on the `frame M that acts as a guide and support. To the arm Q is adj usted and secured a short arm, q, carrying a pin, q. This arrangement, while 4serving other purposes, enables me to dispense with the use of the pin in the curved arm Z, the hooked lever or bar operating on the pin, and the arm and pin on the arm Q, which operates the bar.

The inode of operating my improvements may be thus described:

When the driving-band is shifted from the first to the second driving-pulley A, the following operations take place:

Through the gear B and its connections, the frictioneon'e E1 is put in motion in a direction the reverse of that of the band-pulley E.

At the same timethe pin K2, from the shipper K, moves the clutch E2, whose projections press against the face or disk of clutch E3, and forces it and its collar against theratchet E, which, as already stated, is, set fast on the shaft, and, by a further pressure, forces the shaft itself endwise, and thus brings the band-pnl! leyE into contact with the friction-cone. This, moving in the reverse direction, acts upon the pulley E,

at first stopping and then carryingit with the spindleband, which is no longer driven by the bandfpulley A1 on theV main shaft, vsufficiently far .to reverse the m0- tion of the spindles and loosen the yarn, so that the follower can come down wit-hout breaking it, preparatory to winding on.l

The band, thus carried in the reverse direction, carries with it the band-pulley G and its shaft. This enables the beaks of the pawls G, attached within the rim of the pulley G1, to enter the teeth -of -the ratchet-gear G?, and this, put in motion, winds up on the pulley Gf, the chain. or strap G6, and turns the rock or cop-rail shaft N, to which the half-heart cam H is made fast, and operates the cop rail and the r'ods z and U.

The arm to which the rod U is attached, by the movement of the rock-shaft, pushes forward the rod, so that, as soon as the movement comes to an end, it hasreached the point wherethe upper rod terminates and the pin v', resting upon it,- is ready to descend to the lower one.

During this time the lcverJ has, by its attachment at one end to theI clutch-gear. E3, kept that gear. in such a position that the projections of gear E2 cannot enter thecavities in the former, and, bythe intervention of the other end, has prevented the catch-gear F1 and F from closing. The lever itself has been kept in position by the arm. J 3 acting through the rod or bolt-and slot upon it, and the arm J 3 is maintained in its position by the pin o' resting upon the upper bar of U, as before mentioned; and the pressure' of the vclutch E2 upon E3 has also been such that the bar E5, bent on the collar of the latter, and one end of which is attached to the rear of the pawl E7, has prevented the beak from entering the teeth of the ratchet EG.

When, therefore, the pin c is at the point above mentioned, the friction alone has been sucient 'to back off the yarn,'which is now in readiness to be `wound onto the spindles.

The further pushing of the rod U leaves the pino" without support, and, bythe weight of the arm V, made suciently heavy for that purpose, it drops onto the lonler bar.

This movement brings down the end of the arm J3,

and with it the arm of the lever J to which it is connected, and which has presented an, obstacle to the closing of the gear VF1 F". These gears being thus freed, close immediately, and the connection is formed whereby the pulley A puts in motion the gears-for running the carriage in.

At the same time the other arm of lever J rotates the clutch E, so that its openings are brought opposite to the projections of 'E2 which, under the pressnre before mentioned, enter at once into them, and the pressure ceases. 'llie shaft thus relievedis forced by the spring E endwise, removing the band-pulley E from contact with the friction-cone El, and the friction is destroyed. By the movement of the clutch E3 the rear of the paw] El, connected to the bent bar E5, is tripped, and the beak is put into gear with .the

I ratchet E, this gearing of the pawl into the ratchet connecting the -gea-r EE with the band-pulley E, and through a train of wheels with the rack D4. `Motion to the band-pulley is given by andvthrough the rack D,

the reverse of that given bythe friction, andin conformity with the speed of the rack, fast or slow.

vcop rail yet to move until the carriage is in, when the pin q', by the rotation of the arm Q, is brought up under the arm V, and with it, raises the pino suiciently high. to release its hold, and, by the weight of.

the cop rail, the rod is drawn back. The pin o then, released from the action of the pinv q', rests upon the upper bar. A

' At this moment the shipper K transfersthc belt to the first pulley, .causing the clutch EZ, through the` pin K2, to leave the clutch-E3, and, at the same time,

by the movement of the arm J 3, caused by the lifting of the arm V by the pin q', t-he clutch E 'is turned ou the shaft, and the end of the lever is brought up under the catchgear F3. This completes the winding-on motion, and .the carriage is now ready to run out. l v

Havingthus fully described the Anature of my improvements and the-mode of operating them,

Wh'at I claim therein as new, and desire to secure by Letters Patent, is-

1. The loose pulley E, connected with and driven from the main pulley A, in the manner substantially as and for the purpose of reversing the spindlein the mason, or other similarly-constrncted self-acting mules.

2. lhe mechanism, substantially as described, for detachiug the friction-pulley Ell from the band-pulley E and connecting the latter with the loose gear E", for the purpose described. i

3. The band-pulley G, connect-ed withl and operating the rock-shaft and its connections, substantially as described.

4. The arms J, J3, and operated simultaneously by the pin q at the completion of the inward run of the "carriage, to jhold the running-in catch-gear F1 apart,'and place the part of the clutch E3 in proper position to be operated upon, as described, at the completion of the outer run of the carriage to close the friction-,pulleys and back off.

5. The combination with the arm :of the rock-shaft N, of the arms U U1, and arm V, provided with pin c', operating substantially as described, for the purpose specitied. o o
